Research protocols by use case
Eight research-context overviews of peptide combinations grouped by the underlying biology being targeted — sleep, sarcopenia, cognitive decline, skin ageing, recovery, immunity, mitochondrial dysfunction and metabolic syndrome.
The protocol pages bridge the gap between individual peptide profiles and the underlying ageing biology they target. Each entry surveys the mechanism being addressed, the most-relevant peptides, the available stack combinations discussed in the research literature, the evidence base and the UK regulatory framing.
The framing is research-context only. None of the protocols on this site is a licensed therapeutic intervention in the United Kingdom, and we do not provide dosing guidance or therapeutic recommendations. Specific clinical questions belong with a medically qualified specialist, not with this site.
Peptides researched for sleep architecture
Peptides studied for slow-wave sleep, melatonin restoration and circadian alignment.
Peptides researched for sarcopenia and age-related muscle loss
Peptides studied in age-related muscle loss, mitochondrial myopathy and GH-axis decline.
Peptides researched for cognitive decline
Peptides studied for neuroprotection, cognitive ageing and neurodegenerative-disease research.
Peptides researched for skin ageing and dermal repair
Peptides studied for collagen synthesis, dermal remodelling and photoageing reversal.
Peptides researched for recovery and tissue repair
Peptides studied for wound healing, connective-tissue repair and post-exertion adaptation.
Peptides researched for immunity and immunosenescence
Peptides studied for T-cell maturation, dendritic-cell function and immune restoration.
Peptides researched for mitochondrial dysfunction
Peptides studied for cristae stabilisation, mitokine signalling and NAD⁺-axis preservation.
Peptides researched for metabolic syndrome
Peptides studied for insulin sensitivity, visceral adiposity and metabolic-syndrome biology.
